The Yokomo ZR-118S is an R/C-scale battery spacer designed for use in on-road chassis. It functions as a simple positional shim to move the battery slightly within the tray so you can tune balance without modifying the battery pack.
To fit the spacer, place it between the battery and the tray or mounting surface and secure with your tray's existing strap, screws, or tape as required. Ensure the installation is secure and check for any interference with the body or connectors.
In practice the ZR-118S is used to tweak weight distribution to influence traction and steering feel on asphalt or carpet layouts. Pair it with adjustments to ride height, battery orientation, or damping when refining setup. This description refers only to R/C-scale models and components.
